Why this guide exists
Texting is the highest-response channel an auto shop has. Customers ignore voicemail and email but read a text in minutes. That’s exactly why the rules matter — the same channel that books brake jobs can land you in trouble if you use it carelessly.
Two sets of rules govern business texting in the US: the TCPA (Telephone Consumer Protection Act), which is federal law about consent and contact, and A2P 10DLC, the carrier registration system that decides whether your texts even get delivered. Most shop owners don’t break these rules on purpose. They break them by accident — texting a number that never consented, missing a STOP reply, or blasting at 6 a.m.
This guide is the playbook the Car Mechanic Snapshot enforces by default, so compliance isn’t something you have to remember on a busy day.
Step 1 — Capture written consent
Before you text a customer marketing or reminder messages, you need their consent, and you need a record of it. The cleanest way is to capture it on your booking and intake forms with clear language right above the submit button — something like “By providing your number, you agree to receive text messages from [Shop Name] about your service. Reply STOP to opt out.”
The snapshot’s forms ship with this language built in. When a customer books online or fills out an intake, consent is captured and logged automatically — no separate paperwork, no advisor having to remember to ask.
Step 2 — Register for A2P 10DLC
Even with consent, your texts won’t reliably reach customers unless your shop’s number is registered for A2P 10DLC. This is the carriers’ system for verifying that business texting comes from a legitimate, identified sender. Unregistered traffic gets filtered, throttled, or blocked outright.
We handle this registration for your number during install. It can take a couple of days for carrier approval, which is why we start it early in the launch process.
Step 3 — Honor opt-outs instantly
When a customer replies STOP, that’s the end of texting them — immediately and automatically, across every workflow. There’s no “we’ll get to it.” A missed opt-out is one of the most common and most expensive TCPA mistakes.
The snapshot handles STOP (and the usual variants) automatically. The moment a customer opts out, they’re suppressed from all outbound texting, and it’s logged. Your advisors don’t have to do anything, which is exactly the point — relying on a human to catch every STOP is how shops get burned.
Step 4 — Identify your shop and keep it relevant
Every text should make clear which shop it’s from. A reminder that just says “your appointment is tomorrow” with no shop name is both confusing and non-compliant. The snapshot stamps your shop name into messages and includes opt-out language where it belongs.
Keep the content relevant, too. Texts tied to a real service — an estimate, a reminder, a review request after a completed RO — are well within bounds and welcomed by customers. Random blasts unrelated to anything they asked for are where shops get into trouble.
Step 5 — Text within reasonable hours
Sending a review request at 6 a.m. or a reminder at 11 p.m. annoys customers and pushes against the rules. Stick to reasonable daytime and early-evening hours.
The snapshot enforces quiet-hours windows automatically. If a workflow would otherwise fire a text in the middle of the night, it holds the message until an appropriate time. You set it once; it protects you on every send after that.
Step 6 — Log everything
If a question ever comes up about whether a customer consented or what you sent them, you want a clean record, not a guess. The snapshot keeps an audit-ready log of consent captured, messages sent, and opt-outs honored — exportable if you ever need it.
The bottom line
TCPA and A2P 10DLC sound intimidating, but the practical version is simple: get consent, register your number, honor STOP instantly, identify your shop, text at sane hours, and keep records. The reason to let the snapshot enforce all of this by default is that compliance can’t depend on a busy service advisor remembering the rules on the worst day of the week. Build it into the system once, and it just runs.
